2.0-5.0 Ton Hand Pallet Truck

How does the structural design of the 2.0-5.0 ton hand pallet truck frame ensure the stability and safety of the pallet truck when it is under heavy load? Are there any designs such as reinforcing ribs and supporting structures to improve the strength and rigidity of the frame?

In the field of modern logistics and industrial equipment, hand pallet trucks are the simplest, most effective and most common loading and unloading and handling tools in pallet transportation tools. Their structural design is directly related to operating efficiency, operational safety and long-term reliability. HECHA, as a forklift manufacturer with professional focus as its core competitiveness and keeping up with the development direction of international modern industrial and logistics equipment convenience, intelligence, energy saving and environmental protection, has also devoted profound technical background and innovative spirit to the design of manual pallet trucks. Especially in the heavy load range of 2.0-5.0 tons, the structural design of the manual pallet truck frame of HECHA has brought stability and safety to a new level.
When designing the frame of the manual pallet truck, HECHA follows a series of basic principles to ensure the stability and safety of the vehicle when it is under heavy load:
Strength first: As the supporting skeleton of the entire pallet truck, the frame must have sufficient strength to withstand the pressure when fully loaded to avoid structural deformation or damage.
Rigidity guarantee: While maintaining strength, the frame must also have sufficient rigidity to resist torsional deformation under external forces and ensure stability and precision during operation.
Lightweight design: Under the premise of meeting strength and rigidity requirements, the use of materials is reduced through optimized design, the weight of the vehicle is reduced, and operational flexibility and energy efficiency are improved.
Easy to maintain: The frame structure should be convenient for daily inspection and maintenance, reducing maintenance costs and downtime.
In order to ensure the excellent performance of the frame under heavy load conditions, HECHA cleverly uses stiffeners and support structures in the frame structure design:
Rib design: HECHA uses precisely calculated stiffeners in key stress-bearing parts of the frame, such as the connection between the crossbeam and the longitudinal beam, and the middle of the longitudinal beam. These stiffeners not only increase the cross-sectional inertia moment of the frame and improve the bending strength, but also effectively disperse the concentrated load and reduce the stress concentration phenomenon, thereby significantly improving the overall strength and durability of the frame.
Support structure design: In response to the special needs of heavy-duty pallet trucks, HECHA has designed a multi-point support structure at the bottom of the frame, including but not limited to cross support, triangular support, etc. These support structures form a stable triangular or quadrilateral force system through reasonable layout and size design, which greatly enhances the torsion resistance and overall stability of the frame. Especially when operating on turns or uneven roads, the support structure can effectively prevent the frame from twisting and ensure safe operation.
In addition to innovations in structural design, HECHA also focuses on the selection of materials and optimization of heat treatment processes to further improve the performance of the frame:
High-strength steel: The main body of the frame is made of high-quality high-strength low-alloy steel (HSLA steel), which not only has excellent mechanical properties and weldability, but also can reduce weight while ensuring strength, meeting the requirements of lightweight design.
Heat treatment strengthening: Heat treatment of key components of the frame, such as quenching and tempering, is performed to improve the microstructure of the material, increase hardness and toughness, thereby enhancing the fatigue life and load-bearing capacity of the frame.
While ensuring the strength and rigidity of the frame, HECHA also attaches great importance to safety protection and humanized design:
Anti-slip design: The surface of the pedals and handrails of the frame is anti-slip, ensuring that the operator can maintain a stable standing and grip in a slippery environment, reducing the risk of accidental slips.
Buffer device: Buffer blocks or anti-collision strips are set at the front and both sides of the frame to reduce damage to the frame and surrounding objects during collisions and protect the operator from injury.
Ergonomic design: The height, angle and handrail position of the frame are ergonomically optimized to ensure that the operator can maintain a comfortable posture and reduce fatigue during long-term operations.
The frame design of HECHA's hand pallet truck not only integrates the above-mentioned advanced technologies, but also has obtained multiple patent protections, reflecting the company's strong strength in technological innovation. In addition, the company's products have passed the ISO-9001 quality management system certification, European CE certification and strict testing by the China National Engineering Machinery Quality Inspection Center, ensuring that every link from design to production meets international standards and industry specifications, providing customers with safe and reliable logistics equipment solutions.
